the answer is a(n) equationequationWhen two expressions are equivalent they can form an equation.
A statement that equates two equivalent expressions is called an Identity.

Two expressions that equal 19 are ( 10 + 9 ) and ( 38 - 19 ). Both simplify to 19, demonstrating that various mathematical operations can yield the same result.
You can use them to find a variable. Lets say you have two equivalent expressions with the same variable... x + 2x - 42 = 0 2x - 28 = 0 If you combine these equivalent expressions you ahve... x + 2x - 42 = 2x - 28 In all of the expressions you have x = 7 There are also other applications but its confusing to explain.
Most expressions.
In many cases you can simplify an algebraic expression. You don't really "solve" them; an equation can be solved. An equation is a declaration that two expressions are equal, for example, x + 3 = 10.

when a symbol such as <or> is placed between two expressions
Two expressions where the solution equals 41 are ( x + 7 = 48 ) and ( 3x - 2 = 121 ). In the first expression, solving for ( x ) gives ( x = 41 ). In the second expression, solving for ( x ) also yields ( x = 41 ).
When two expressions are equal they can form an equation.
when a symbol such as <or> is placed between two expressions
Two expressions that are equal are called "equivalent expressions." These expressions yield the same value for all values of their variables. In mathematics, this concept is essential for solving equations and simplifying expressions.
4x2y8 is an expression, not an equation. Expressions cannot have solutions.
